Big Jack Sprat is a monster in AdventureQuest Worlds.
Big Jack Sprat is a Skeleton anomaly. So old that he passed into Battleon folklore, nobody know how he was raised, what his purpose is, or even if Jack Sprat is his real name. The mausoleum that Big Jack Sprat makes his home is so huge that he must've been someone important enough for an enchanted spear to end up in his possession. Big Jack Sprat's body looks more or less human with the exception of it's jaw and legs that come from different creatures. Some people have theorized that Big Jack Sprat took those parts from the unfortunate animals and monsters that crossed it's path.
